What are common mistakes developers make with default methods in interfaces?

When it comes to using default methods in interfaces, developers often make a few common mistakes that can lead to confusion and bugs in their applications. Here are some of those common mistakes:

• Overusing Default Methods: Developers might implement too many default methods in interfaces, leading to complicated inheritance hierarchies and making it difficult to manage dependencies.
• Ignoring Method Signature Changes: When default methods have an implementation in the interface, changes to their signatures can break existing implementations in classes, resulting in compilation errors.
• Not Leveraging Method Overriding: Some developers may forget that they can override default methods in implementing classes, thus failing to take advantage of polymorphism.
• Mixing Responsibilities: Developers might place default methods into interfaces that manage unrelated functionalities, violating the Single Responsibility Principle.
• Neglecting Documentation: Lack of proper documentation for default methods can create confusion for future developers who work with the codebase.

To avoid these pitfalls, developers should be mindful of their design choices when using default methods in interfaces.
